FEED MECHANISM FOR BALING=PRESSES.

Specification of Letters Patent.

Patented Feb. 12, 1907 Application filed August 1. 1906. Serial No. 328,781.

To (all whom it may concern.- Be it known that I, GILMAN V DAVIS, a i citizen of the United States of America, re E siding at Atkinson, in the county of Holt and State of Nebraska, have invented new and f useful Improvements in Feed Mechanism for Bailing-Presses, of which the following is a 5 specification.

This invention relates generally to im- 1 provements in baling-presscs, 'andparticu- E larly to a feeding and packing mechanism 1 therefor, whereby loose hay thrown into the f hopper may be forced into the baling-chamher in advance of the plunger prior to being compressed thereby.

The object ofthe invention is to provide a 1 simple and effective type of feed mechanism which is operated by the plunger and automatically thrown into and out of action at proper periods. i With the above and other objects in view the invention consists of the novel construcfully described and claime reference being had to the accompanying drawings, in 1 which Figure 1 is a side elevation of a balingi press embodying my invention, showing the feeder in retracted position. Fig. 2 is a top plan view of the same. Fig. 3 is a vertical longitudinal section showing the feeder as it 5 appears just after the beginning of'its working stroke and just prior to the completion of its return stroke. Fig. 4 is a plan view of the carrier-yoke. r Referring to the drawings, the numerall designates the frame of a suitable type of superposed hopper or feed-chamber 4.

5 designates the compressing-plunger, and 6 the plunger ro d or bar, which slides longitudinally in a sultable guide 7.

Fulcrumed in bearings 8, at the rearv of the i hopper, is a yoke 9, preferably constructed, as

shown in Fig. 4, of a pair Of-angriar members 10, provided at their lowerends with trunf nions or journals 11 and having their upper ends bent to form attaching members 12, between which isarranged the rear end of a carrier-bar 13; iwhi'c'h i's bolted or otherwise suitably fasteiied tliereto. To the forward i end of the bar are"p'ivotally connected feed 1 bars or iingersl lfwhich are'pivotallgy joined at their upper ends by links 16, two pairs of t such fingers being preferably employed, one i arranged in advance of the other, the upper ends of the forward pairs being pivotally connected with the hopper by a swinging brace-link 17, whereby the fingers are guided to move in a determined path without material deflection and are stayed in their feeding and bracing action. The'arrns or members 12 of the yoke are freely movable in a slot'18,

formed in the rear wall of the hopper, thus allovting the fingers 14 to swing in an are through the hopper to the position shown in Fig. 1 and from such position down into the 5 upper end of the mouth 3 "of the balingchamber to force the loose hay thrown into the'hopper therein in the path of the plunger 5 prior to its compression by said plunger.

When the fingers are in retracted position, the operating-arms of the yoke 9 extend at a downward and forward angle on opposite sides of the hopper, and said arms are attached to the hopper by coiled springs 19,

which serve to retract the feed mechanism-as a whole. To the trunnions, at the lower ends 9 of the operating-arms of the yoke, are pivot allyconnected a connecting-rod or link 20,

l whereby the yoke is adapted to be coupled to the plunger rod .or bar 6. In the construction disclosed the link or connecting-rod 20 is shown in the form of, a bail, the free ends of the arms of which are provided with bearings 21', pivotally engaging the trunnions 11. The cross portion 22 of this bailshaped link or connecting-rod is adapted for engagement with a catch carried by the plunger rod or bar .6, said catch being in the form ofa metallic strip 23, secure to said rodor bar and bent to form a keeper-recess 24, having spring clampingjaws 25. Arranged on opposite sides of the pin 29 on the bar, whereby the downward swinging movement of the dog is limited.

The lower surface of the dog is inclined and is adapted on the return movement of the bar 6 to ride over upon a retracting member 30,

arranged on the frame 1 adjacent to the guide 7, the action of which member lifts the dog to throw the portion 22 of the connecting-rod 20 out of engagement with the javvjs' 25. As shown, each dog'is provided witha nose or engaging portion 31, having its upper face inclined to engage and exert an upward pressure on the part 22 when said dog is tilted upwardly bythe member 30, thus in suring the forcible release of the connectingrod from the catch on the return stroke of the plunger; Y

' Fig. 1 shows the retracted position of the parts of the feeder, which position they 0- cupy when the plunger is at the limit of its working stroke; When the plunger moves 'rearwardly, the connection 21 is drawn upon to swing the yoke against the resistance of the springs 19, whereby motion is communlcated to throw the feeding-fingers downward to force the hay from the hopper into the mouth 3 of the bailing-chamber, the fingers 14 acting to pressv the hay into the mouth at the time the plunger reaches its fully-retracted position, as shown in Fig. 3, At this time-the inclined lower surface of the dogs 26 come into contact'with the retracting-ele ments 30 and are lifted thereby, thereby throwing the connecting-rod 20 out of engagement with the latch and releasing .it 7

from engagement with the bar 6, thus leaving the feeding attachment free ,;to be returned to normal position by the sprin s 19. The feeder then assumes the position. s own "in Fig. 1, and as the bar 6 moves forward on the ensuing working stroke of the plunger 5 the portion 22 of the connecting-rod slides upward on the inclined surface of the latch and drops into engagement with the jawsat the time the plunger reaches thelimit of such movement. The feeder will then be 0 erated on the following return stroke of t e' plunger to force another supply of hay into the mouth of the baling-chamber, as will be readil understood, the operation of ht'rowing t e feeder into and out of action at proper eriods being thereby automatically accomp ished. i
